2 is a conceptual diagram showing the operation of the seller device according to an embodiment of the present invention.

In Fig. 2, a method for a seller device to upload sales item image information (seller) is disclosed.

Referring to FIG. 2, when the seller registers the sale item 200, it may request registration of the article image on the article transaction application on the seller device based on the information on the sale item 200.

For example, when the sale item 200 is a bag, an image required to register the bag as the sale item 200 may be determined and an image may be requested. Alternatively, it is possible to request imaging of the sale item 200 by using a video imaging function.

The goods trading server may determine a video surface required for goods trading based on the goods sold 200. For example, a three-dimensional article may require six sides, and a flat article may require only two sides.

According to an embodiment of the present invention, it is possible to generate sales product image information (seller) 250 by imaging the sales product image in a plurality of rotational directions with respect to the sales product 200.

When the sale item 200 is three-dimensional, it rotates 360 degrees in the first direction 210, rotates 360 degrees in the second direction 220 (or rotates A degree in the first direction 210, second direction 220) As shown in FIG. B, imaging of the sale item 200 may be performed through rotation and first-side imaging). In general, since the image is processed by placing the sale item 200 on the floor, for example, the first surface may be the bottom surface. Based on the first direction rotation and the second direction rotation, a 360-degree image of the sale item may be obtained.

The goods trading application may determine the first direction 210 in consideration of the shape of the goods to be sold 200. The first direction 210 may be a direction parallel to the xy plane when assuming the position where the merchandise is placed as an xyz coordinate system.

The goods trading application may induce photographing in the first direction 210. On the merchandise trading application of the seller device, a user interface (eg, direction indicator) for inducing rotation of the first direction of rotation angle (eg, 360 degrees) in the first direction 210 may be output.

When the imaging angle deviates from a threshold angle or more based on the first direction 210, the goods trading application may request re-photographing from a specific location. Product image information at a point where a difference of more than a threshold angle occurs may be output, and imaging based on the first direction 210 may be performed from the corresponding product image again.

When the imaging in the first direction 210 is finished, the rotation angles of the second direction 220 and the second direction 220 may be determined based on the imaging result of the first direction 210. The second direction 220 may have not yet been obtained based on the first direction 210, or may be a direction in which additional image acquisition is required. For example, the second direction 220 may be a direction parallel to the xz plane in the xyz coordinate axis. The second direction 220 may be determined in consideration of the imaging result of the first direction 210. The direction for more accurately generating an omnidirectional image of the article based on the imaging result of the first direction 210 may be determined as the second direction 220.

In the same way, after the determination of the second direction 220, the goods trading application may induce shooting in the second direction 220. On the merchandise transaction application of the seller device, a user interface (eg, direction indicator) for inducing rotation of the second direction rotation angle (eg, 180 degrees) in the second direction 220 may be output.

In addition, according to an embodiment of the present invention, the goods trading application may determine an image capturing distance when shooting in the first direction reference and shooting in the second direction reference. A distance capable of imaging the characteristics of the sold article in detail while including the overall shape of the sold article may be set as the article imaging distance. For example, once the shape of the sale item is imaged through the camera of the seller's device, the sale item is 80% of the screen area, background, considering the size of the sale item at the minimum distance based on the minimum distance that can be expressed on the screen as a whole. The article imaging distance can be determined to occupy this 20%. Through this method, it is possible to prevent a phenomenon in which a part of an image of a sale item is not captured because the image of the item is photographed as closely as possible.

The sales goods image information (seller) 250 generated in the above manner can be edited and used to generate sales goods image information (goods sales server), and the goods sales server is sold goods image information (seller) 250 Based on the, it is possible to determine the defect of the goods to be sold.

3 is a conceptual diagram showing the operation of the goods sales server according to an embodiment of the present invention.

In FIG. 3, a method for determining a defect existing in a sale product by the product sale server is disclosed.

Referring to FIG. 3, the article sale server may search for an image of the same article as the article of sale. The product sales server may search for an image of the same item as the product to be sold and collect images through an image search function.

The merchandise sales server may determine the reference image 300 of the merchandise sold by combining the collected images. The collected image may be an image captured from various angles with respect to the sale item, and when combining the collected images with respect to the sale item, an image in all or some areas of the sale item may be obtained. The merchandise sales server may generate a reference image 300 of the merchandise sold by combining images collected based on the basic shape of the merchandise sold. When a plurality of images are collected for the same area of the sale item, an image of the best quality among the plurality of images may be selected as the reference image 300. Alternatively, an image when the sale item is a new product may be collected as image information (new product) of the sale item. The article sales server may determine the reference image 300 by determining an image that is determined to have no defects among images collected, or an image that is determined to be a new product (or an advertisement image or an image for selling a new product).

The reference image acquisition area and the reference image non-acquisition area may be divided based on the sale product. The reference image acquisition area may be an area where an image of a sale item is acquired, and the non-reference image acquisition area may be an area where an image of the sale item is not acquired.

The product sales server may search for a defect area by comparing the sales product reference image and the sales product image information (seller) based on the reference image acquisition area. The search may be expressed in terms of a reference image acquisition area search 320.

Next, the product sales server may search the defective area of the product based on its own defect sales algorithm for the reference image non-acquisition area. The search may be expressed in terms of a reference image non-acquisition area search 340.

The reference image acquisition area search 320 may match the judgment reference point of the reference image 300 with the judgment reference point of the sale product image information (seller), and determine a critical angle based on the judgment reference point to determine defects. .

The reference image non-acquisition area search 340 is a case where the reference image 300 does not exist, and a defect determination is performed by using the learned result based on the defect image that occurred in the same / similar product as the existing sales product. Can be.

Hereinafter, in an embodiment of the present invention, a reference image acquisition area search 320 and a reference image non-acquisition area search 340 are disclosed.

4 is a conceptual diagram showing the operation of the goods sales server according to an embodiment of the present invention.

4, a method for searching a reference image acquisition area for determining a defect existing in a sale item is disclosed by the product sale server.

Referring to FIG. 4, the determination reference point 430 may be determined to perform a reference image acquisition area search.

The determination reference point 430 may be a center point of the image area of the widest angle of view among at least one reference image 400 included in the reference image acquisition area. For example, if the collected reference image 400 includes the first side image 410 and the second side image 420 of the article, among the first side image 410 and the second side image 420 The center point of the image having a wider angle of view may be set as the determination reference point 430.

Alternatively, the determination reference point 430 may further consider the quality of the collected reference image 400. For example, the judgment reference point 430 may be set by further considering whether the collected image is an image having a threshold value or higher.

Alternatively, the determination reference point 430 may be set for each collected reference image. When there are multiple reference images, the center point of each of the plurality of reference images may be set as the judgment reference point 430. In this case, a plurality of judgment reference points 430 may be provided.

After the determination of the determination reference point 430, the determination reference point 430 of the reference image 400 and the determination reference point 440 of the image information of the seller (seller) 450 are matched, and the determination reference points 430 and 440 are referenced. The critical angle can be determined to analyze the difference from the merchandise sold. The threshold angle may be determined based on the angle of view of the reference image 400.

An image difference area in which a difference exists between the reference image 400 and the sale item image information (seller) 450 may be extracted.

Through the defect determination on the extracted image difference region, it may be determined whether the image difference region is a region including defects. Defect determination for an image difference region may be performed based on a defect determination algorithm as in the case of searching for a reference image non-acquisition region.

Hereinafter, in the embodiment of the present invention, a defect determination algorithm is disclosed in more detail.

5 is a conceptual diagram illustrating a defect determination method according to an embodiment of the present invention.

In FIG. 5, a defect determination process for a sale item is disclosed. The defect determination process may be performed for defect determination in the image difference region 500 and the reference image non-acquisition region 520 extracted after the reference image acquisition region search.

Referring to FIG. 5, the product sales server may perform learning on defective photographs. In the present invention, for learning about defects, labeling of defect images that may occur for each product may be performed. For example, learning may proceed by labeling the item name of the bag with respect to a defect image that may occur in the bag. Through such learning, learning about defects that may occur for each product is progressed, and a procedure for determining defects in an image difference region and a reference image non-acquisition region may be performed. Such defect learning may be continuously performed based on a defect image accumulated through a transaction between a seller and a buyer.

Through the defect determination procedure, a specific region may be determined as a defect in the image difference region and the reference image non-acquisition region, and a candidate defect region image 530 that is an image of the region determined as the defect may be extracted.

The defect determination result information including the candidate defect area image 530 may be transmitted to the seller device. The seller may check the defect based on the defect determination result information received through the seller device. The seller can check the part that is judged to be not a defect and request the trial panel to the goods sales server again. Upon request of the judge, the judgment request image corresponding to the result of the defect determination may be captured again and transmitted to the goods sales server. The trial request image is an image corresponding to the candidate defect area image 530 and may be an image for receiving a trial on whether the defect is defective.

The product sales server may specify and provide an area corresponding to the candidate defect area image 530 on the item to request the trial request image 540. For example, when a seller clicks on a specific candidate defect area image 530, an indicator indicating an area corresponding to the corresponding candidate defect area image 530 on the item may be provided on the goods transaction application of the seller device. Alternatively, when the seller clicks on the specific candidate defect area image 530, the camera application is operated, and a part corresponding to the candidate defect area may be displayed as a separate indicator.

The goods sales server may perform a defect analysis again based on the request image 540 of the judges to perform a judgment on whether the goods are defective. As a result of the judgment, if it is determined that it is not a defect, the candidate defect area image 530 corresponding to the corresponding request image 540 may be excluded from the final defect image.

The candidate defect area image 530 that is not requested by the seller by the seller and the candidate defect area image 530 determined as a defect as a result of the judge may be determined as the final defect image 550. The final defect image 550 may be included in the sale product defect information (item transaction server) and transmitted to the purchaser device that wants to purchase the sale product. A portion determined as a defect in the final defect image 550 may be displayed as a separate indicator.

6 is a conceptual diagram illustrating a method of generating image information of a sale item in an article transaction server according to an embodiment of the present invention.

In FIG. 6, a method for generating sales product image information (product transaction server) through editing of sales product image information (seller) is disclosed.

Referring to FIG. 6, image information (seller) of a sale item may be information captured based on the first direction 610 and the second direction 620.

The merchandise transaction server may perform editing on the merchandise image information (seller) to provide the buyer with an image of the merchandise more clearly.

The goods trading server may correct the image based on the first direction 610 and the second direction 620. For the convenience of checking the seller's merchandise on the screen, the omnidirectional image of the merchandise photographed based on the first direction 610 and the second direction 620 is corrected in the horizontal and vertical directions based on the monitor. You can.

After the direction correction is performed by the goods trading server, the area excluding the object image may be deleted through object recognition. Through object recognition, an object area and a non-object area may be distinguished, and a part corresponding to the non-object area may be deleted.

Thereafter, the commodity trading server may set the image direction and the image angle to remove the remaining images except for the image corresponding to the specific direction and the specific angle. For example, only images of the imaging distance interval b are left in the a direction 610 and the remaining images can be removed. The basic image of the article provided to the purchaser is an image of the imaging distance b in a direction, and according to the buyer's request, an image of the imaging distance interval d in more detailed c directions for the article can be provided. At this time, c may be a value greater than a, and d may be a value less than b.

Through this method, the buyer may not feel an inclination to the image of the sale item, and only the necessary image may be provided. In addition, the merchandise sales server may reduce the load of data processing and transmission by providing an image of a merchandise that is adaptively detailed according to a buyer's request rather than initially providing all images of the merchandise.

7 is a conceptual diagram illustrating a method of determining a name of a product for sale in a product transaction server according to an embodiment of the present invention.

In FIG. 7, a method is disclosed in which a commodity trading server generates sales commodity name information (commodity trading server).

For ease of search by the purchaser, the sale item name information (item transaction server) 750 may be added so that it is possible to search by a name other than the sale item name information (seller) 700 determined by the seller.

The merchandise sales server may perform a search for sales items registered with names other than the merchandise name information (seller) 700 for the merchandise based on the merchandise image information (seller) 700 for sale.

Based on the search results, it is possible to determine the sales item name information (article transaction server) 750 according to the search results.

As a result of the search, the product name used in a proportion greater than the name of the seller of goods sold (seller) 700 for the same item, the percentage of the product was not used in a proportion greater than the name of the seller of goods sold (seller) 700 for the same item, but a critical percentage The product name used above may be extracted.

The product name used in a proportion greater than the sales item name information (seller) 700 for the same item is the first level item name 710, and the proportion greater than the sales item name information (seller) 700 for the same item The item name that is not used as but is used as a threshold percentage or higher may be the second level item name 720.

In this case, the first level item name 710 and the second level item name 720 may also be added to the sales item name information (seller) to determine the sales item name information (the goods transaction server).

When a buyer searches for the first level item name 710, the item sold for the item name information (seller) for sale may also be exposed in the search result. That is, even in the case of searching by the first level item name 710, sales items not registered as the first level item name 710 may be included in the search result and provided to the buyer. However, after being preferentially provided as a result of the search of the sales item registered as the first level item name 710, a sales item registered as sales item name information (seller) may be provided next.

In addition, when a buyer searches for the second-level article name 720, the sale article corresponding to the sale article name information (seller) may be exposed in the same search result. That is, even in the case of searching by the second level item name 720, sales items not registered as the second level item name 720 may be included in the search result and provided to the buyer. However, there is a separate priority in the search result between the sales item registered as the second level item name 720 and the sales item registered as the sales item name information (seller), so that the second level item name 720 is registered. After the sale item, the sale item registered as the first level name, the sale item registered as the sale item name information (seller) may be searched.

The merchandise sales server may provide information about the first level merchandise name 710 and the second level merchandise name 720 to provide an opportunity for the seller to modify the merchandise name information (seller).

8 is a conceptual diagram illustrating a method of providing sales item data of an item sales server according to an embodiment of the present invention.

In FIG. 8, a method is disclosed in which an article sale server provides sale article information according to a buyer's search.

Referring to FIG. 8, it is important for the product sales server to quickly and accurately provide a desired sales item among items desired by a buyer.

When the buyer inputs 'A' to search for item A, the item sales server may provide a plurality of sales item information 800 registered by a plurality of sellers corresponding to A.

Priority for providing information of the plurality of sale items information 800 may be determined in various ways. The sale item information 800 of the sale item in which the transaction is completed may be excluded, or the priority of the sale item information 800 of the sale item in which the transaction is completed may be provided with the lowest priority.

The information providing priority of the sale item information 800 may be determined in consideration of buyer response information 810, sale item price information 820, and sale item defect information (item transaction server) 830.

The buyer response information 810 may include information on the buyer's reaction to the sale item. For example, the buyer response information 810 may include a buyer's clickthrough rate on a sale item, a time spent on the sale item page, a comment left on the sale item, and a buyer's purchase attempt.

The sale item price information 820 may include information on the price of the sale item set by the seller.

The defect information of the goods for sale (the goods transaction server) 830 may include information on defects present in the goods for sale. Instead of the sale goods defect information (item trading server) 830, the grade information on the quality of the sale goods divided based on the sale goods defect information (item trading server) 830 may be used as the sale goods defect rating information.

9 is a conceptual diagram illustrating a method of determining an information providing priority of a sale item according to an embodiment of the present invention.

In FIG. 9, the information providing priority of the sale item may be determined in consideration of buyer response information over time.

Referring to FIG. 9, buyer response information may include a click-through rate for a sale item over time, a time spent on the sale item page, a comment left on the sale item, and a buyer's purchase attempt.

Referring to (a) of FIG. 9, the click-through rate for the sale item over time is after the first click-through rate 915 and the first threshold time 910 during the first threshold time 910 after the sale item is newly raised. The second click rate 925 during the time period and the third click rate 935 during the period before the second threshold time 920 based on the current time may be included.

Different click weights are assigned to the first click rate 915, the second click rate 925, and the third click rate 935, so that the reference click rate can be determined. Can be determined. The reference click-through rate is determined by weighting in the order of the third click-through rate 935, the second click-through rate 925, and the first click-through rate 915. As this age increases, the reference click-through rate may be relatively low. However, the degree to which the reference click rate is changed to a relatively low value may be changed in consideration of the time after registration in consideration of whether the same / similar product is frequently registered.

Referring to (b) of FIG. 9, the longer the time spent on the sale product page is, the higher the priority of providing information on the sale product may be. Similarly, the time spent on the sales item page is the time at which the first page remains during the third threshold time 930 after the sales item is newly uploaded, and the second page stays during the time period after the third threshold time 930. The third page remained time 955 during the section before the fourth threshold time 940 based on 945 and the current time.

Different weights are assigned to the first page stay time 935, the second page stay time 945, and the third page stay time 955 to determine the stay time on the reference page, and the higher the reference page stay time It may be determined as a priority for providing information of a relatively high selling product. The reference page stay time is determined by weighting in the order of the third page stay time (955), the second page stay time (945), and the first page stay time (935). In consideration, the longer the total time elapsed after registering the sale item, the lower the reference page stay time may be. However, the degree to which the reference page stay time is changed to a relatively low value may be changed in consideration of whether the same / similar product is sold frequently.

In addition, the priority of providing information of the sale item may be changed based on the comments left on the sale item and the purchase attempt of the buyer.

Through the analysis of the comments left on the sale item, the priority of providing information on the sale item may be changed by distinguishing whether it is a positive comment on the sale item or a negative comment on the sale item. A positive comment on a sale item may be a positive evaluation of a sale item or a seller, and a negative comment on a sale item may be a positive evaluation of a sale item or a seller. The goods sales server can distinguish positive comments from negative comments based on the learning result of the existing comments, and the information providing priority of the goods sold may be changed based on the classification.

In addition, as the number of purchase attempts by the buyer is relatively high, the priority for providing information on the items to be sold may be set relatively high. However, if a purchase is not established after an attempt to purchase, the priority of providing information on the sale item may be adjusted through a search for a reason for not purchasing after the purchase attempt of the purchaser.

10 is a conceptual diagram illustrating a method of determining an information providing priority of a sale item according to an embodiment of the present invention.

In FIG. 10, the information providing priority of the sale item may be determined in consideration of the sale item price information and the sale item defect information (item transaction server).

Referring to FIG. 10, the goods sales server may collect price information and sales goods defect information (goods trading server) of the same / similar sales goods.

First, the product sales server may collect the price information 1000 of the same existing sales item and the defect information of the sales item (the goods transaction server) 1020 of the existing sales item which is the same as the sales item.

The article sales server may determine an appropriate price 1040 of the current sale article based on the price information 1000 of the existing sale article and the defect information of the sale article (item transaction server) 1020 of the existing sale article. The merchandise sales server may search the transaction history of the collected transaction information with the same defect level as the sold merchandise sold within a threshold time based on the current time point. The defect level may be determined based on the defect information of the goods sold (the goods transaction server). Defective grades may vary by product. The higher the price of the product, the higher the standard for defects according to defects is set, and the longer the expected life of the product, the higher the standard for defects according to defects may be set. The price of the product is the price when the corresponding product is a new product, and the expected life of the product can be determined based on input values of a plurality of sellers for the product. Further, in order to determine the defect level, judgment on the type of defect, the degree of defect, and the cost of healing the defect may be performed.

Among the defects classified based on the above-described learning, whether the defect is a possible healing or not and the cost of repairing the defect may also be progressed. Information on whether a defect can be healed for each item by a separate defect repair management device. Information on the cost of repairing a defect can be input, and based on this input, through continuous learning, the type of defect and the defect of each defect are sold. Determination of the extent and defect healing cost can be performed.

According to an embodiment of the present invention, an appropriate price of a current sale item may be determined based on a defect grade. An appropriate price of a current sale item considering a defect level of a current sale item may be determined in consideration of a sale price of each defect level of the previously sold product.

11 is a conceptual diagram illustrating a method of performing a price deal between a seller and a buyer according to an embodiment of the present invention.

11, a method of performing a price deal between a seller and a buyer on a sale item is disclosed.

Referring to FIG. 11, a method of performing a price deal between a seller and a buyer based on a seller's request price 1120 and a buyer's request price 1100 is disclosed.

When the appropriate price 1150 of the current sales item is determined, the difference between the sales request price 1120 and the purchase request price 1100 may be determined based on the current sales item appropriate price 1150.

If the difference between the request price for sale (1120) and the appropriate price (1150) of the current sale item is greater than the difference between the purchase request price (1100) and the fair price (1150) for the current sale item, the purchase price is first increased with the purchaser device. You can ask the seller to try a price deal with the set suggested purchase price.

At this time, the recommended purchase price may be determined in consideration of the current purchase request price 1100 of the purchaser, the purchase request price of another purchaser, and an appropriate price 1150 of the current sale item.

A price deal may be performed by performing n division on the basis of the difference between an appropriate price 1150 of the current sale item and a purchase request price 1100 of the current buyer. If the price difference is 10000 won and n = 5, the price is increased in units of 2000 won, but the price can be increased only below the limit line (for example, 8,000 won) that the current buyer wants.

In this case, the n division value may be determined in consideration of the purchase request price 1100 of another buyer. The n value may be set to be smaller as there are relatively many other buyers who want to purchase a sale item.

In addition, as there are more other buyers, a price deal may be performed by performing n division based on a difference between a price that is n% higher than the appropriate price (1150) of the current selling item at a reasonable price and a purchase request price of the current buyer.

If the difference between the request price for sale (1120) and the fair price (1150) of the current sale item is less than or equal to the difference between the request price for purchase (1100) and the fair price (1150) for the current sale item, the price is dealt in the same manner as above. The procedure can be performed.

If the difference between the request price for sale and the appropriate price for the current sale item is less than or equal to the difference between the purchase request price and the current price for the current sale item, the seller first places a price deal on the buyer with the suggested sale price with the seller device set the selling price lower. You can ask to try. At this time, the recommended selling price may be determined in consideration of the selling price of the current seller, the selling price of the other seller, and the appropriate price of the current selling item.

A price deal may be performed by performing n division on the basis of the difference between the proper price of the current selling item and the current seller's selling request price. If the price difference is 10000 won and n = 5, the price is reduced in units of 2000 won, but the price can be reduced only below the limit line (for example, 8,000 won) that the current buyer wants.

In this case, the n division value may be determined in consideration of the selling price of another seller. The n value may be set to be smaller as there are relatively many other sellers who want to sell the same sale item.

In addition, as there are more other sellers, a price deal may be performed by performing n division based on the difference between a price that is n% lower than the appropriate price of the current selling product at a reasonable price and the selling price of the current seller.
